This file primarily contains well locations and associated inorganic and isotope chemistry sample analyses for wells sampled for the Carlton County Geologic Atlas, Part B. It also contains data from the Minnesota Pollution Control Agency Ground Water Monitoring and Assessment Program and Minnesota Department of Health. Chemistry data are managed in a MS Access database. Excel tables of chemistry data are available online for download at water chemistry data access page.
